forgive me vishal but these all icon which are supported by icon tweaker makes my PC tooooo slow as compared with manual change of the icons i have copied shell32.dll of windows 7 and open with restorator in xp and exact the icons those icons works perfectly...(not with the help of icon tweaker)

Thank you, thank you, THANK YOU. I've spent what feels like an eternity cruising the internet, trying to find a proper, easy-to-use Win7 icon set for XP. Now, at last, my search has ended. I do rather wish you'd let the icons go up to 64 instead of dinky ol' 48, but hey. I'll take it.
